A method for setting more precisely a position and/or an orientation of a device head in a measuring environment by a distance measuring device which has a number of M, M≥1, distance measuring sensors and which is connected to the device head. A control device is communicatively connected to the distance measuring device and an on-board sensor device. The position and/or the orientation of the device head is determined by the on-board sensor device and the position and/or the orientation of the device head determined by the on-board sensor device is set more precisely by the control device.

A system and method for forming a structure with steep walls (walls having an angle greater than 60° with respect to a level plane) through one or more incremental sheet forming operations is provided. The method includes a workpiece with an inner region and an outer region that are separated by a boundary region. The boundary region includes a plurality of openings and a plurality of connecting elements. The openings are cut into the workpiece using a boundary region cutting tool. A forming tool is configured to operate on the inner region after the boundary region cutting operation has been completed. At least one control unit is in communication with the forming tool. The at least one control unit operates the forming tool to form the structure from the inner region.

A cutting machine includes a tool holder for holding the tools required for chip-removing machining of a workpiece, and a tool arm connecting the tool holder to a drive unit, which moves the tool arm to align one of the required tools with a workpiece in each manufacturing step. The tool arm includes an upper arm connected with the drive unit and mechanically connected to a lower arm. The lower arm is connected with the tool holder. At least one force transducer is positioned between the upper arm and the lower arm so that during chip-removing machining of a workpiece, the force transducer is capable of measuring a tool force exerted by any of the required tools in a main flow of forces.

The present invention discloses a multi-degree-of-freedom numerical control turntable including: a B-shaft rotating assembly; a C1-shaft workbench swing assembly; a C2-shaft workbench rotating assembly; and an S-shaft workbench movement assembly. The B-shaft rotating assembly includes a rotating connection land and a B-shaft power control mechanism; the C2-shaft workbench rotating assembly includes a movement base, a workbench and a C2-shaft power control mechanism; the S-shaft workbench movement assembly includes a swing base and an S-shaft power control mechanism; and the C1-shaft workbench swing assembly includes a swing arm and a C1-shaft power control mechanism, with the C1-shaft line intersecting the B-shaft line. The S-shaft power control mechanism can drive the movement base to move along an S-shaft line on the swing base to cause a region to be machined of a workpiece to approach the intersection point of the C1-shaft line and the B-shaft line. The present invention adds the C1-shaft and S-shaft, so that when the cutting edge point participates in the motion, the coordinate change of the linear shaft is smaller, the compensation range of the linear shaft is smaller, the machining efficiency is higher, and the surface quality and machining accuracy are less affected by the accuracy of the linear shaft.
